Be it iniow'n' thet we, Biennium P. Remy and FRAIQK I. REMY, ofAnderson, county of Madison, 'a'nd'Sttte of Indiana, have invent "eda-ceftain"n'ew' and useful Magneto-ElectrieGenemtor; and We do herebydeclare "that' the following is a fuil, cleiir, and exact descriptiontherebf, reference being had to the'eccompanying'drawings.

This'invent'ion relates to the disposition et the pints of an electricgenerator in such manner afsto produce an efficient and easilyconstructed apparatus, and has been made with particular reference tothe c0nstr1ic-' apart, between which the Winding 'is a'r-f tiondf amhghetoelectric-gencrator for ignition purpnses.

The chief feature of 'the invention consists in nidunfingghe'm'fmaturein a non-revoluble position r'e tive to the rotary inductors,

sziidarmature including pole pieces spaced IangeisnidnTmature being out'of the field of rotationof-the inductors;

Another feature consists in the mounting of mid armature so estopermitof its posi' 'tion' being changed; and providingan interrupter that is.controlled by the change of position of the armature whereby the time'of interruption may bevmed.

The nature of the invention will be understoodfibmithe followingdescription and claims and the accompanying drawings.

Fi 4 is a diagram of thecircuits by which t e ignition of an internal combustion engine may beproduced by this generator, but the particular arrangexnent of circuitsused is ho veter not essential to the invention.

In the drawings herein there is shown a base 10 ,fo'rtli'e generatorwhich is ma'de prefembl'y of non mzfgrfetic material, and there are no"upwardly extending sides, as

the inner set'of magnets lI rest upon the base.

The outer set of magnets 12 do not extend as low as the base, asindicated in Figs. 1- and. 2 but these features are immaterial.

The complete pieces and'en'd plates 17 and '18"is'relatively and ntrmny stetionaryrthht is; the armetare is notrevblvedor'mov ed by the'revoliir tion of theinduetor shaft or any"other' revolving me'mber. But the armature is not stationaryaltogether;- as" it is cnpabl'e of being oscilmeiroek orinevednsindicated armatfire, including the core, winding, nine lie 5peak.

Integral with the end plate 18 and bearin extension 16 therefrom thereis a timer disk 30 which carries an insulated terminal 31 --adapted tobe touched by the contact lever 32, which lever is normally pressedtoward said terminal by a spring 33 lying between said lever anda post31 on the timer disk, see Fig. 1. The lever is actuated by the doublecam 35, which is secured to the inductor shaft adjacent the disk 30..There fore, at each revolution of the inductor shaft said cam actuatesthe lever 32 and makes and breaks the circuit twice. Since the switchportion of the circuit breaker, namely, the terminal 31 and lever 32 aremounted in connection with the oscillatory or rocking armature costruction, when the armature is rocked or s ifted, say from the positionshown by full lines in Fig. 1 to that shown by dotted lines, theposition of thelever 32 relative to the cam 35 will be modified, andthereby the time at which the circuit is made and broken is varied.

In Fig. 4 there is shown a diagram of circuits illustrating thearrangement of parts of the generator and electrical apparatus externalthereto by which ignition may be produced. In that diagramAO. is theprimary'winding of an induction coil and 4:1 is the secondary winding,the latter having relatively many turns when compared with the former,and 42 is the core'thereof.

43 represents the spark plugand 4-1 the condenser.

27 represents the armature winding and from that a wire 45 runs to theprimary winding in the induction coil, and a wire it runs from theprimary winding to the terminal 31, and a wire runs from the circuitbreaking lever 32 to the winding 27 of the armature. The terminals ofthe secondary winding 41 are connected to the respective terminals ofthe spark plug.

The action of the generator is as follows:

When an-inductor 22 is in proximity to an armature pole piece 26 and thefield magnet pole piece 19, as indicated ire-Fig. 2, it forms betweensaid pole pieces a path for magnetic flux. The inductors 22 aref'soplaced that when one armature pole piece 26 is thus connected withonefield magnet pole piece 19, the other armature pole piece 26 is con--nected to the other field magnet pole piece 19 at the other end of thedevice." A path for magnetic flux is thus, formed starting from thefield magnet, through a field magnet pole piece, an inductor, anarmature pole piece, the armature core, the other armature polepiece.'the other inductor. the other field magnet pole piece, to thefield magnet. The

' versed.

-thesecondary inductors 22 are so disposed that when the inductor shaftand associated parts revolve through half a revolution, the direction ofthe flux through the armature core is' re- The reversals of flux in thearmature core occasioned by the revolution of the revolving partsserveto induce an elec tromotive force in the windings 27.

In'order to produce ignition, the current from the winding is ledthrough the primary of the induction coil and at a suitable instantinterrupted by the separation of the contact lever 32 and the contact31, occasioned by the action of the cam. This sudden stopping of thecurrent in the primary of the induction coil induces in thereof anelectromotive force sulliciently great to jump the gap in the sparkplug. The condenser serves to diminish the spark formed between theinsulated contact 31 and the contact lever at the instant of separation.To vary the time of interruption and consequently the time at which thespark occurs in the spark plug, the immature is shifted about the axisof the shaft, as indicated by'full and dotted lines in Figs. 1 and 2,thereby moving the contact lever as hereinbefore described.

, Although but two inductors 22 and two 95 drawings-the invention is notlimited to this armature pole pieces 26 are shown in the riouscharacters in the various windings. I,

Also it is immaterial whether the field magnct pole pieces 19 areseparate from or intcgral. with the magnets, as they act as onev means.The same is true of the armature core and armature pole Pieces 26.

In order to make the mode of operationobtain a satisfactory spark it isdesirable u Hwiucluced clecti-omotirc t'n'ce posses. s a.high value. '17 Referring to l 5. the rear inductor 22, which is uppermost, forms aconnection between the rear armature pole piece 26 and that the circuitlnmkcr open the circuit at its the right hand field magnet pole piece19.

The magnetic. liux through the armature eta-e is small, on account ofthe magnetic C11- a at the same speed as the crank shaft. order to varythe time of sparklng, the disk teale9 cuit being open between thefront-armature pole piece and the front inductor. By the time thattheifnductors have turned through a, small angle, to the position shownin Fig. 6, the front inductor has closed the magnetic circuit betweenthe front armature pole piece and the left hand field magnet pole piece,thereby closing the magnetic circuit and allowing the flux through thearmature core to increase rapidly. This rapid increase. in the fluxresults in a high value of; the induced electromotive force. Thus, byshifting the armature, the most desirable point for the interruption ofthe circuit by the contact points is also shifted.

In use, the gearing between the magneto and the engine is such that thecam interruptsthe circuit every time that a charge is to be ignited. If,for example, the engine be of t-he'four cylinder, four cycle type,making two explosions per revolution of the crank shaft, the magnetoshould be drivpn n is turned about the axis of the shaft,

- thereby changing the position of the inductors at which theocircuit isinterrupted, but this movement-of the disk 30 causes the armatur; toperform a. similar movement, thereby changing the most favorable instantfor the interruptionof the circuit to correspond with the change of theinstant of interruption.

Although the description here given assumes that the front inductor ison the left, and the rear one on the right, it is evident that similarconditions occur when the opposite is the case, one half of a revolutionof the shaft. later, but with the flux in the core.

opposite direction through the armature There are therefore two pointsduring the revolutiop of the inductors at which a good spark may beproduced.
